Specification of Letters lnatent.

Patented Jan. 3, 1922.

Application led May 21, 1919. Serial No. 298,737.

`of a forepartsection anda rear section.

the sections being united at the shank portion of the sole.

Oner object of the invention is to provide av strong and durable connection between the sections, the only evidence of lwhich visible at the outer side 0f the sole. is a butt joint extending across the shank portion.

Another object of the invention is to provide a pieced sole, the rear section of whirh is composed of' a. plurality of relatively thin layers, and adapted to be manufactured at a relatively small expense, and to be securely connected with a forepart section having` suitable wearing qualities, and composed, for example, of sole leather.

To these and other related ends, the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings forming a part of this specification,-

Figure 1 is a view of the bottom` or tread side of a sole embodying the invention..

Figure 2 is a view of the opposite sido of the sole.

Figure 3 is a fragmentary sectional view showing the rear end portion of the forepart section. Y

Figure 8a is a view similar to Figure 3, showing a modification.

Figure d is a fragmentary sectional view, showing parts of the two sole sections before they are united.

ligure 5 is a fragmentary sectional view. showing parts of the two sole sections after they are united, and before the fastenings hereinafter described are concealed at the outer face of the sole.

Figure 6 is a section on line 6-#6 of Figure 2..

Figure 7 is a view similar to Figure 8, showing a modification.

' Figure 8 is a view similar to Figure. G, showing another modification.`

The same reference characters' indicate the same parts in all of the gures.

In the drawings, 12 represents the forepart section of a sole, this section being preferably a single piece of sole leather, as

indicated by Figure 3, although, if desired,

the forepart sect-ion may be' composed of a relatively thick body layer 12'DE of sole leather or the like, and a thinner layer 12b.

The rear end portin of the section 12 is formed by spaced apart outer and inner tongues 13 and 14, the section being preferably split. as indicated at 15, to form the inner side of the tongue 13. The inner tongue 14 is spaced from the outer tongue either by the removal of some of the material. or

by compression of the material to forni aV surface indicated by the dotted line 16 (Figure said surface vbeing the outer side of the tongue 1li. The inner side of the section 12 is preferably rebated to further reduce the thickness of the tongue 14 and form a shoulder 17 at the base of the tongue. lhen the section is constructed as shown by Figure 3, the shoulder 17 is formed by one end of the layer 12b.

The tongues 13 and 1a are provided respectively with end faces 17 and 1S, which are perpendicular to the sides of the section and are preferably in the same plane.

The forepart section includes the tread portion and a. part of the shank portion of the sole. The rear section next described includes the heel and a part of the' shank portion of the sole, said rear section being indicated as a whole by the reference numeral 19. The rear section is provided with outer and inner end faces 22 and 23, which abut against the end faces 17 and 18 of the forepart section, and form .outer and inner butt joints, indicated at 20 and 21 in Figures 6 and 7, the outer butt joint 2O being on the outer or tread face of the sole. The rear section is provided with .outer and inne-r tongues 2li and 25, projectingn from the end faces 22 and 23, and alternating with the tongues of the forepart section.

The rear section 19 is preferably composed of a lurality of layers, which may be of any suitalble material, such as split leather, or skivings, or other material suitable for the purpose. Said layers are of different lengths, there being a shorter layer 19"L interposed between two longer layers 19." The inner end face 23 of the rear section is formed by the forward end of the shorter Vas through each of the tongues, said.

layer 19a, The outer end faceY 22 is formed by the end of a single layer 19C which forms the outer face of the rear section.

I prefer first, to assemble all the layers of the heel section, excepting the layer 19., and then engage the rear section with the forepart section, as indicated by Figure 5, ythe outer tongue 13 of the forepart section being turned back. The tongues 2a and 2li of the rear section may be cemented to the inner tongue 14 of the forepart section, and are preferably additionally united to said inner tongue by fastenings extending fastenings being preferably stitches Q7. After fastenings are inplace, the outer tongue 13 is turned down and cemented to the adja` cent tongue 24C to form the outer` butt joint 20 and conceal the fastenings 27.

I prefer to unite all the layers of the heel section, excepting the outer layer 19, by similar fastenings 27, inserted before the outer layer 19c is applied. The application of the layer 19c completes the outer butt joint 20 and covers the fastenings 27a. The outer layer 19c is preferably secured in place by cement.

It will now be seen that the two sections are firmly united in such manner that there is` no evidence of the pieced construction at the outer face of the sole, excepting the butt joint 20. Owing to the fact that the end faces forming this butt joint are perpendicular to the side faces of the sole, the joint is durable and not liable to be opened by wear. The laminated construction of the rear section enables the latter to be made of relatively inexpensive material or materials, and yet possess suiicient strength and durability.

Figure 7 shows a modification, in which the rear section is made in a single piece, instead of being laminated, the tongues 24 being integral with the body of the rear section. In this case the rear section may be made of a quality of leather or other material which ischeaper than that of which the forepart section is composed.

The rear section 19 may be composed of two layers 19d and 19e, as shown by Figure 8. The forward end of the longerflayer 19e forms an inner tongue 25a. The cuter .tongue 24 is formed by a separate piece bearing on an inwardly offset seat on the layer 19d, and is covered by a tongue Y30 which is integral with the layer 19d.

It will be seen that the forepart section has a solid wear-sustaining portion, which includes the tread face, and is 'of greater thickness than either of the layers of the rear section. When the forepart section is made in one piece, the thickness of its solid wear-sustaining portion exceeds the aggregate thickness of the layer 19a and the two layers 19". When the forepart section is the' Y Ving the abutting faces 22 and made in two pieces, as shown by Figure 3, the thickness of its solid wearsustaining por tion exceedsthe aggregate thickness of the layer 19EL and one of the layers 19h. When the rear section is composed of two layers, as shown by Figure 8, the solid portion of the forepart section is thicker than either of said layers.

It will be understood that when the sole is incorporated in a shoe, the rear section is raised by the curvature of the sole abovethe tread face of the forepart section, no wear beingsustained by the rear section,so that the rear section may be made'l upof layers of relatively ycheap material, without deoperation of assembling saidlayers produc- 23, and the tongues 24 and 25.
